    Steering rack swap caused SRS light to illuminate?

    Hey guys, I’ve owned my 1991 e30 with the original airbag wheel for ~3 years. Before the rack swap, the SRS functioned correctly - SRS light illuminated solidly for 6 seconds after turning car on then extinguishes permanently the remainder of the drive.

    I had a shop swap a used remanufactured steering rack in and now the light blinks continuously. They were unsuccessful in getting the light to turn off or reset. The mechanic took the car to a bmw specialty shop with the SRS reset equipment and they were unable to reset the light because “unable to communicate with module. Recommend replacing ABS computer.” I didn’t know the ABS computer was connected to the SRS system?

    Also, when I got the car back after the swap, the steering was extremely light, would almost skip when driving over a chip or bump on the freeway and the wheel would not return to center after a turn. We figured it was just a bad rack because it was used with an unknown history. Now that I got the car back after a week of them fussing with the SRS light, the steering is heavy and tight and the wheel returns to center after a turn. any ideas on why that would be?


    What could be the cause for the SRS light blinking and solution here?

    Thank you,

    The procedure doesn't need any special equipment.
